Guide overview

Before you begin

Burned out tail lights may have severe effects on not only the person driving the vehicle, but on other drivers on the road. For example, a burned out tail light can delay the vehicle inspection process, which is a requirement for registration of a vehicle in Texas. A vehicle that is not properly registered in Texas will result in a citation, and possible towing of the vehicle. Purchase the replacement bulb at an auto parts store. To find the correct bulb, ask the employee to look up the make and model of your mustang for the correct reverse light bulb.
